Frequently Asked Questions
Who may download NEW?
The NEW system is free for academic purposes.
How do I get help with NEW?
Our staff is very limited, and though we are willing to
offer you some help in getting started, we cannot offer any
significant technical support. As you probably know, this is the
policy for most open-source software. But we have tried to anticipate
questions and difficulties in our documentation, so we hope you will
be able to set up and use NEW readily. Feedback from you is welcome.
This web site for NEW (http://netlab.gmu.edu/NEW/) includes a
download page - use the "download" link in the menu on the left side
of the NEW home page - that provides download links for the NEW
client, server and web management pages. Several versions are
available and all are compiled code. We suggest you use the newest
one. These downloads each contain a README file with
extensive instructions. You should begin with the Server download.
(Note: the "Open Source" link on the NEW home page goes to the page
with download links for the NEW source code.)
Can I use the NEW software with Windows XP?
We have experienced no problems running NEW under Windows XP.
Can I use NEW with Windows Vista?
Yes, NEW will run under Windows Vista. Please note that the installation requires
On the download web page, it says that the size of the NEW Client is 10MB.
Unfortunately, when I downloaded it, I only received 163KB. What did I do wrong?
When you allow all of the tools to load, it will be at least 10MB. The tools will
load if you allow the download to execute as set in the zipfile. Alternately, you can
install just the master client and then click on newadd.bat.
The clients that I downloaded do not have Floor Control.
Is it the way it should be?
In NEW releases through 4.0.0, the Floor Control does not load until the first
time it is used in an online session.
I have installed NEW client on windows XP home edition.I am not able to find
these following files: DEMO-LIVE.nwc and DEMO-PLAY-STREAMING.nwc in the NEW
These files are not found locally on your system but sent from the web server
when connecting to the live server.
You can test the NEW client by going to http://netlab.gmu.edu/disted or
http://disted.ite.gmu.edu depending on which course you are enrolled in
and using the selecting "Test your connection" on the welcome after you
I am using Windows Vista and get the message, "error in 16-bit waveInOpen testing format" when starting NEW.
What should I do?
For many users this problem has been remedied by updating the audio drivers on their system. Try visiting
your system manufacturer's support website and installing the latest audio device drivers. If this does
not fix your problem, send email to firstname.lastname@example.org
I tried to download and install, but I get an error message saying to install
java 1.4. I think I did download J2SE 1.4.2. Is there another option?
Try uninstalling all versions of java on your machine. Then goto
and download the latest 1.5 by clicking the 'download now' button. If you need the
JDK, try the
The problem is that java isn't in your path and NEW isn't able to find it on
your system. A proper installation should remedy this.
Does the NEW install program use the JAVA_HOME environment variable to find the
installation of the JDK?
The installation program tries several ways to locate Java 1.4 runtime. JAVA_HOME
is on the list; but it tries the Windows registry first. If there is a problem
with the registry setting, JAVA_HOME will not be consulted. Reinstalling Java 1.4
typically resets the registry values.
When I try to install the NEW software with my Windows 98, I get an error message
about the installer. What should I do?
Download and install the Windows Installer from Microsoft. You can download
My NEW installation freezes. The console reads:
NEW Master Client 040300 starting java cmd:
"C:\Windows\System32\java.exe" -classpath "C:\PROGRA~1\NEW\NEWC040204" testJava14"
What should I do?
You should install (or reinstall) the Sun's Java Runtime Environment from
When installing the client, the application fails with the message, "NEW client
software download failed." What should I do?
If you are connecting from behind a web proxy server or have local firewall software
running, such as Norton Internet Security or ZoneAlarm, try disabling these while
installing NEW. Or you could configure your security system to grant access to the
NEW java application. NEW needs to connect to the Internet to download additional
components during the initial installation and may need to do so again later to
When I installed NEW, why didn't I get an icon in the programs menu?
NEW does not install an icon in the programs menu. It is a client for Web
access, and as such it is not normally run independently of a webpage. The NEW
clients will be invoked when you access the webpage https://netlab.gmu.edu/.
You also can run PLAY-STANDALONE in C:\Program Files\NEW by clicking on it, if
you have downloaded NEW recordings and want to play them standalone. If you
want an icon for PLAY-STANDALONE on your desktop, you can make a shortcut or
just copy the file to your desktop.
How do I connect to NEW for a live class using my browser?
For a detailed description, choose the link for your browser:
My Speak Freely window says it cannot support the audio format. What should I do?
This is a Windows problem and the answer is to reboot.
I normally use 800x600 monitor resolution and there just is not enough room for
everything. Do you have any suggestions?
If you are not planning to ask spoken questions, run the LISTEN-ONLY version of
NEW. It has a smaller GUI.
Though I can hear the instructor with the NEW software, he cannot hear me.
What should I do?
First ensure sound is working on your computer. Use the "sound test" button on the
NEW Speak Freely panel. It will capture a short segment from your microphone
and play it back.If the green bar does not bounce when you speak, either your
microphone is not working or the volume needs to be increased. If the bar bounces,
but you do not hear sound coming back soon after, either your speakers/earphones are
not working or the play volume needs to be turned up.
I am running 64 bit Linux and I keep getting error messages about missing whiteboard
libraries. What should I do?
With Linux Red Hat install these libraries:
yum install glibc.i686
yum install libstdc++.i686
yum install libX11.i686
yum install libXScrnSaver.i686
using your apt-get command.
For non Red Hat based distributions, look for the libraries in their
respective package managers, e.g. on Ubuntu use apt-get or search in
I am getting disconnected from my live class repeatedly. What can I do?
There are several sources for this problem. Check for them with these steps.
First, if you have been connecting with video, try connecting without it.
Second, reboot your machine before connecting with NEW. This is especially
important if you have not rebooted for some time.
Third, see if your disconnects are due to your web connection. If other
network applications are sluggish, NEW will not be able to work, because it needs
streaming delivery of at least 56 kb/s.
Fourth, be sure there is no background application running on your machine
such as messenger/AIM or a P2P program.
, check your machine for spyware/worms/viruses that may be creating
general instability and/or saturating your network connection. Try installing
and running an anti-virus scanner. Look in the task
manager for DLLHOST.EXE or SVCHOST.EXE. These can be legitimate processes, but
if the names are all capital letters, it may be the w32 welchia worm. To eliminate
worm, run the tool at Symantec
website. You may safely run this tool whether you have the worm or not.
When I send a message to the professor, it is displayed in the window for text received.
Do the other online students see that message?
Typing in the pink text window sends messages for the instructor alone to see.
The white text window is a chat area for all participants to see.
How about adding student microphones to NEW?
If you are going to add student microphones, they need to be combined through a mixer
with the instructor microphone, not brought in through NEW running on student machines.
The half-duplex sound in NEW assumes no two machines are within sound reach of each other;
otherwise you get feedback.
There are basically three options for the student mics:
1. leave them open all the time- this results in a great deal of noise
going out on the net and into the recording.
2. voice-activate the mics- this is expensive and ends up being just the same
as #1 because any cough, dropped item, etc. activates the mic.
3. have the students push a button to activate--this results in the instructor
constantly saying, "Push the button on the mic before you speak."
Bottom line: Our experience shows student mics are not a good use of money,
instructor time, class time, or technician time. I strongly prefer a single
wireless mic that can be worn by the instructor and passed to a student who has
something long to say. (A two-channel system with one worn by the instructor and
the other available to pass around is even better. In this case, the second should
be hand-held not clip-on.) When the student has a short question or comment, the
instructor should repeat or paraphrase it for the group. This is actually the
best teaching technique in any case, whether you are online or not.
When I try double clicking on PLAY STANDALONE, I get the following error:
"unable to connect to record/playback server - continue anyhow? (click CANCEL
to quit)." Could you tell me how can I solve this problem?
This is usually a symptom that you do not have Java installed. See the downloads
page for a link to get it.
When I playback a class, sometimes the slides seem to be out of order. Why?
There was a bug in the playback resequencing. When the instructor went forward
a slide, and then back, the slide did not in fact go back. So all the marks got
made on the wrong slide. This bug has now been fixed so future classes will not
have this problem. We are resequencing the files of past classes, but this may
take some time.
Why do the slides not play properly when I change classes on playback?
The whiteboard caches slides as received. You should restart NEW when you go to
the second class and the problem will not occur.
Can I see the recordings of past semesters' courses?
It is now possible to access recordings from the previous semesters, for students
who were enrolled in the courses at that time. Take the 'Past semesters' link on
the menu of the logon page and choose the semester, then logon with your user
name and password.
I would like to stop and come back to the same point in a lecture recording, but
when I use the forward button to position the recording, the slides and the
instructor's markings get out of sync. What should I do?
The recording works by playing back a stream, so what you want is virtually
impossible. However, the player is built to skip forward by exactly one slide
each time you click the double-arrow-forward button. If you do that, you'll get
to see the slide.
Is it possible for me to use NEW to make a recording?
Yes, you can make your own recording and play it back with NEW. Follow these
